How Many Toothpicks Are Needed To Build The Tree On Day 100?

Answers

Answer 1

Answer:

100 x 4 = 400 - 91 = 309

Step-by-step explanation:

Answer 2

Answer:

100= 4 + 3 (100-1)

4+3 (99)

4 + 297 is 301

Step-by-step explanation:

The first row starts with 4 toothpicks, and they increase by +3 in each row.  The first tree is already accounted for which makes the 4 + 3, and why I have 100-1.  The teacher said the answer was correct but I doubted the equation.  Can you tell me if this is correct?

Hillside orchard grows Fiji apples and Gala apples. There are 160 Fiji apple trees and 120 Galla apple trees in the orchard. Hillsides Orchers owners decide to plant 30 new gala apple trees. find the number of new Fiji apple trees the owner should plant if they want to maintain the same ratio of Fiji apple trees to gala apple trees

Answers

The number of new Fiji apple trees needed to maintain the same ratio is 40 trees.

Ratio

Ratio is the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.

The ratio of Fiji apple to Gala apple = 160 : 120 = 4 : 3

If 30 new gala trees are planted, hence the number of gala trees increases to 150 (120 + 30). To maintain the same ratio:

Number of fiji apple = (4/3) * 150 = 200

New Fiji apple trees = 200 - 160 = 40

The number of new Fiji apple trees needed to maintain the same ratio is 40 trees.

Answer:

y = -1x + 2

Step-by-step explanation:

We need to find y = mx + b

Use the following equation

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Plug in the values

[tex]\frac{-1-0}{3-2}[/tex]  = [tex]\frac{-1}{1} = -1[/tex]

We have found the slope(m) which is -1

We have to find y-int b

Plug in any given x,y into the slope formula

-1 = -1(3) + b

-1 = -3 + b

2 = b

At last the formula is

y = -1x + 2

what is the answer to -4(2d+3)+2(-d+4)?

Answers

Answer:

-10d-4

Step-by-step explanation:

Well, you're in luck because I LOVE distributive property!!!

-4(2d+3) Multiply -4 by 2d to get -8d, and multiply -4 by 3 for -12, so the result would be -8d-12!

Then, 2(-d+4) and therefore 2 times -d (you can just say -1d) to get -2d and 2*4 would be 8 to make -2d+8!

Now you combine them: -8d-12+-2d+8

Combine like terms!

-10d-4 would be your answer.

A ranger hiked 601 feet to and from the peak of a​ mountain, each way. The ranger hiked 2 times in the past eight weeks. How far did the ranger hike on the mountain over the past eight ​weeks?

Answers

Answer: 2,404 feet

Step-by-step explanation:

Each way was 601 feet. Going up was 601 feet and coming down was the same.

Total for both is therefore:

= 601 + 601

= 1,202 feet.

They did this twice in 8 weeks:

= 1,202 * 2

= 2,404 feet
